7 Claims.

The present invention pertains to a bottle closure for bottles containing fluids such as, milk, cream and the like. The invention is described herein with reference to a milk bottle, but this is merely by way of illustration, and it will beunderstood that analogous uses are also contemplated.

The desirability of a closure that covers the pouring lip of the beverage bottle has long been recognized. Closures serving this purpose are now in use and consist for the most part of a molded stiff cap adapted to be set in position. The high cost of such devices has restricted their use to the higher priced dairy products, to the exclusion of moderate and cheaper priced grades of milk that are sold in far greater volume than the more expensive products.

The object of the present invention is to provide an inexpensive closure of this character, that is so cheap that it may be used on even the cheaper grades of milk. Itconsists first of a flexible sheet of waxed paper, cellophane, metal foil or the like adapted to cover the mouth and enclose the pouring lip of the bottle. Across this sheet is fastened a strip for the purpose of carrying an ordinary stiff cardboard disk for insertion in the seat of the bottle mouth. At the ends of the strip are secured to the overhanging edges of the sheet, preferably by means of a punch and. fold, and a disk is stapled exclusively to this strip, whereby the sheet prevents contact of the contents with the staple. Finally, the overhanging part of the sheet is secured against the bottle neck by means of a surrounding band, the ends of which are also stapled together.

In order to prevent contact with the milk if a cellophane or metal foil sheet is used, a supplementary strip is fixed on the other side by the same punch fold means. The center of the last strip is in a form of a disk, concentric to the ordinary stiff cardboard but larger in diameter, and is placed on the seat of the bottle mouth.

The invention is fully disclosed by way of example in the following description and in the accompanying drawing of which- 7 Figure 1 is a side elevation of a bottle equipped with a cap according to the invention;

Figure 2 is a vertical section thereof;

Figure 3 is a top plan view of the cap before being applied to the bottle;

Figure 4 is a section on the line 4-4 of Figure 3, and

Figure 5 is a plan view of a modification.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figures 1 and 2 is shown the neck I of aconventional milk bottle having at its upper end a bead 2 within which is formed a seat 3 for receiving a bottle cap.

The cap itself includes a sheet 4 of a suitable flexible material such as waxed paper, cellophane, metal foil or the like. Diametrically across the sheet and on the upper surface thereof is laid a strip 5 which may also consist of any of the materials previously mentioned. This strip has its ends secured to the sheet 4 near the edge of the latter by a punch and fold 6 made by a suitable instrument or machine designed for the purpose.

Upon the strip 5, at its center, is laid a disk I similar to the usual fiat disk ordinarily used for reception in the seat 3. The disk is held to the strip 5 by a staple 8 but it is to be noted in this connection that the staple does not pass through the sheet 3, as may be seen in Figure 2, whereby the sheet prevents contact of the milk with the staple.

When the sheet 5 is mounted over the mouth of the bottle it becomes crimped and ruffled as indicated by the numeral 9. A band I0 is then applied around the edge of the sheet 6, thereby. bringing the overhanging part of the sheet into close contact with the outer surface of the bottle neck. The end parts of the band I Dare fastened together in any suitable manner, as by means of a staple I. One of the ends is preferably extended at I2 beyond the fastening H to provide a finger piece for releasing the band to permit 35 removal of the sheet t and parts carried thereby. In closing the bottle again before consuming all of the contents, the disk I may be again inserted in the seat 3 at least as easily as is now done in the case of a simple disk used in the bottle closure. If it is desired to take still more precaution, the over hanging part may again be brought against the neck of the bottle and held in position with an elastic.

When it is desirable that the sheet l be insulated from the contents of the bottle, such as when the sheet 4 is of cellophane or metal foil, another strip I3 is placed under the sheet 4. Said strip I3 is cut in the form of a disk [4 larger than the disk 7 and placed concentric to the latter. Same punch fold is used for holding strip I3 to the sheet l.

In the modification shown in Figure 5 there are two strips 5 mounted across the sheet 4 diametrically and at right angles to each other. The

stiff disk 1' is held by a staple 8' at the intersection of the strips.

Among the advantages of the invention, it will be seen that the bead or lip 2 of the bottle is covered by the sheet 5, thereby maintaining the bead or lip in a clean and sanitary condition, which is very desirable inasmuch as the milk must be poured over this part. Further, the sealing of the sheet is effectively provided by means of the disk i, the effectiveness of which is well known in the art. However, the fastening for holding this disk in the assembled closure is shielded from contact with the milk by the central portion'of the sheet 4 as previously described. Finally, the device is inexpensive, requiring no molded parts which have hitherto been necessary in covering the pouring lip. The various parts of the device, with the exception of the disk I which is of stiffer material, consist of such materials as paper, cellophane, metal foil or the like the sheet 4 being preferably waxed or water-proofed.

The strips 5 and 5 and the band it! may be pro-- ,vided in distinguishing colors, thereby adding attractiveness and distinctiveness to the device, if desired. Finally, the closure lends itself to reapplication to the mouth of the bottle after a part of the contents has been poured off, as already described above.

This closure may be mounted and secured on the bottle'with the same speed as in present practice, by means of specially designed machinery.

Although specific embodiments of the invention have been illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention, as indicated by the appended claims.

What we claim is:- 1. A bottle closure comprising a sheet of sufiicient size to enclose the mouth of a bottle, a strip secured to the said sheet, a disk fastened to'said strip and adapted to seat in the mouth of the bottle, the fastening being entirely above said sheet.

2. A bottle closure comprising a sheet of sumcient size to enclose the mouth of a bottle, a strip secured to the said sheet, a disk fastened to said strip and adapted to seat in the mouth of the bottle, the fastening being entirely above said sheet, and a band for holding said sheet around the outside of the neck of the bottle.

3. A bottle closure comprising a sheet of sumcient size toenclose the mouth of a bottle and overhanging in contact with the outer surface of the bottle neck, a strip crossing said sheet and secured to the overhanging part thereof a disk fastened to said strip and adapted to seat in the mouth of the bottle, the fastening being entirely above said sheet.

4.

5. In combination with a bottle having a seat' in its mouth, a sheet covering the mouth and overhanging in contact with the outer surface of the bottle neck, a strip crossing said sheet and secured tothe overhanging part thereof, a disk fastened to said strip and mounted in said seat, the fastening being entirely above said sheet, a band holding the edge of said sheet against said neck, the end parts of said band being fastened together. i

, the fastening being entirely above said sheet, a

band holding the edge of said sheet against said neck, the end parts of said band being fastened together, one end of said band being extended beyond the point of fastening to provide a finger piece.
